public static Byte[] GetDateDetail(string ip, int port, Byte[] received){ 

var encoding=Encoding.UTF8;

Utils.tuxputenv(string.Format("WSNADDR=//{0}:{1}", ip, port));

AppContext appContext = AppContext.tpinit(null);

//发送给tuxedo服务器的字符串参数

TypedBuffer sendBuffer = new TypedString(string.Format("Tuxedo Service {0}", 　　　　　　encoding.GetString(received)));

//用于接收tuxedo返回的结果

TypedBuffer revBuffer = new TypedString("");

appContext.tpcall("TOUPPER",sendBuffer, ref revBuffer, 0);

string outPut = ((TypedString)revBuffer).GetString();

appContext.tpterm();

return encoding.GetBytes(outPut);}

我现在想直接将Bytes[]作为参数和返回结果，这样写为什么不对？

TypedCArray sendBuffer = new TypedCArray(1024);

sendBuffer.PutBytes(received);

//用于接收tuxedo返回的结果

TypedBuffer revBuffer = new TypedCArray (1024);

...

appContext.tpcall("TOUPPER",sendBuffer, ref revBuffer, 0);

....

return ((TypedCArray )revBuffer).GetBytes();

tpcall就异常了。不知何故啊，求解答。
